ALBANY — The College of Saint Rose went into lockdown for about an hour Saturday night as police searched for three men who attempted to rob a Hudson Avenue resident at gunpoint.

Albany police spokesman Officer Steve Smith said about 9 p.m. police received a report of gunfire at a home in the 500 block of Hudson Avenue. Three men armed with handguns attempted to rob the resident. One shot was fired but no one was hit. The suspects fled before police arrived. It's believed the home was targeted because of alleged marijuana sales there, Smith said.

Saint Rose reported on its Facebook page that police searched the campus for the suspects, as it alerted students and staff through social media to shelter-in-place, meaning to stay inside buildings. The lockdown and shelter-in-place were lifted at 9:52 p.m. Saturday.
